Yes, standard amplitude modulator includes a carrier and two sideband frequencies. In DSCSC only sidebands are there but the carrier is suppressed so I think the answer is B.

Balanced modulator-A modulator in which the carrier and modulating signal are introduced in such a way that the output contains the two side-bands without the carrier.
But standard amplitude modulator includes upper-side and lower-side frequencies and the carrier frequency.

In the question upper side, lower side and carrier frequency including. carrier not suppressing. Then what is the correct answer?

The generation of DSB-SC modulator is present the both lower side band and upper side band,so it is the balanced modulator.

Its answer is balance modulator. Because it is the method of generation of DSB-SC system. The std amplitude modulator is nothing.
